ClimbingSpeed and SwimmingSpeed Multipliers

As a Roblox developer, it is currently too hard to make variable speed for humanoid activities.
Some activities, like Swimming and Climbing alter the speed of characters.
It is said on official DevHub as well.

What we know about speeds:

I think we should be able to have more freedom over those speeds.
Maybe we could get stuff like JumpingSpeed as well? Who knows!

If Roblox is able to address this issue, it would give us more humanoid freedom.
Being able to make “Diver” class in some FPS game which moves slow on land, but fast in water?
Maybe we want to make something like Snake Eater’s ladder, but as you climb the speed gets faster?

I would really love those changes.
